Well i might have to go that way if i can’t work this out. But i would prefer to use alsa directly if possible. The reason for me not to use jack, is not that there is anything wrong with it, on the contrary. The reason is just that it doesn’t make sense in my case, i don’t need any inter-app routing for this project, and it would just be another dependency. Adding jack to the mix doesn’t seem like the right solution to the actual problem... it makes for a very nice delay actually :-) fokke
